External adjustment switch The external design of the water adjustment valve is easier to control. The extraction is even and slow over a longer period, which reduces acidity and enhances sweetness. Doublelayer filtration Doublelayer filtration includes a filter plus a replaceable filter paper. The filter itself can be reused, and the filter paper can be replaced when needed. Stainless steel filter The density stainless steel filter effectively filters residues. It helps maximize extraction while reducing sediment and bitterness for a clean, wellbalanced brew tailored to your preference. Material and flow The precision faucet is designed with acrylic material to guide the water flow, delivering about 78 drops in 10 seconds. Use scenarios Home pourover coffee: Use the external adjustment switch to achieve even, slow extraction, lowering acidity and bringing out natural sweetness for a smoother cup. Small kitchen or cafe setup: Dial in extraction for different coffees and roasts with repeatable results, while minimizing sediment and bitterness. Tea or herbal infusions: Employ controlled water flow to improve extraction quality, using a steady rate of flow for a consistent infusion.
